Subject: [PATCH] parisc: dont unconditionally override CROSS_COMPILE for 64 bit.

From: Paul Gortmaker <[email-masked]>

Using the 64 bit toolchains from kernel.org[1], one finds that
you can't build the a500_defconfig, because the Makefile will
stomp whatever value you have in your env. for CROSS_COMPILE.

This shows up since the kernel.org toolchains for parisc-64
do not have the "-gnu" prefix, and so you run into it always
saying hppa64-linux-gnu-gcc not found, regardless of the fact
you've not got "-gnu" put anywhere into CROSS_COMPILE.
